This is a question to all you PR enclosure experts, or anyone who whats to chime in. I was wondering if there is a preferred configuration for the drivers and PR's. In my enclosure I will have 1 AV12 and 2 15" PR's. Is it OK to have the driver firing downward with the PR's on the vertical sides? Or is it better to have the driver front firing and the PR's still on the vertical sides? The holes on my box are already cut, so for me its a matter of the foot print size of the sub. I would prefer a smaller footprint, but it would require the driver to be down firing. Thanks for the advice in advance.
